Pressure on White House to Do More about Gulf Spill as BP Just Kind of Shrugs

It seems that the only people that can make heads roll in the BP oil spill is the Obama administration and some want just that done. BP, for its part says the situation is complicated.

Oil giant BP is briefing the federal government on its internal investigation into the massive Gulf of Mexico oil spill that focuses on two key areas: cementing at the well head and the blowout preventer.

BP said in a release late Monday that its probe has not reached a final conclusion. But it said multiple control mechanisms should have prevented the accident that started with an oil rig explosion April 20.

Tony Hayward, chief executive of BP PLC, called it a complex accident caused by an unprecedented combination of failures.

BP said its investigation team has begun sharing its findings with the U.S. Department of the Interior.
